Service PCB Assembly Services Description: 1. High density possible
Over the years, the high density of printed boards has been able to
develop correspondingly with the improvement of integrated circuit
integration and the advancement of mounting technology.
2. High reliability
Through a series of technical means such as inspection, testing,
and aging tests, the PCB can be guaranteed to work reliably for a
long time (usually 20 years).
3. designability
Requirements for various properties of PCB (electrical, physical,
chemical, mechanical, etc.) can be achieved through design
standardization, normalization, etc. In this way, the design time
is short and the efficiency is high.
4. producibility
PCB adopts modern management, which can realize standardization,
scale (quantization), and automatic production, so as to ensure the
consistency of product quality.

PCB Assembly Services Introduction: The earliest use of printed circuit boards is paper-based
copper-clad printed boards. Since the advent of semiconductor
transistors in the 1950s, the demand for printed boards has risen
sharply. Especially with the rapid development and wide application
of integrated circuits, the volume of electronic equipment is
getting smaller and smaller, and the circuit wiring density and
difficulty are getting bigger and bigger, which requires the
printed board to be updated continuously. At present, the variety
of printed boards has developed from single-sided to double-sided,
multi-layer boards and flexible boards; the structure and quality
have also developed to ultra-high density, miniaturization, and
high reliability. |
